AMENDMENT  TO  REGULATION  41,  PROVIDING  FOR  THE  DIPPING  OR 
THE  QUARANTINE  OF  SHEEP  IMPORTED  FROM  CANADA  FOR  BREED-

U.  S.  Department  of  Agriculture, 

Office  of  the  Secretary, 
Washington,  B.  C,  October  18,  1909. 

Regulation  41  of  the  Regulations  of  the  Secretary  of  Agriculture  for 
the  inspection  and  quarantine  of  horses,  cattle,  sheep,  and  other  rumi- 
nants, and  swine  imported  into  the  United  States,  B.  A.  I.  Order  142, 
is  hereby  amended  to  read  as  follows : 

Regulation  41.  All  sheep  imported  into  the  United  States  from 
Canada  for  breeding,  grazing,  or  feeding  must  be  inspected  at  the  port 
of  entry  by  an  inspector  of  the  Bureau  of  Animal  Industry.  They  must 
also  have  been  inspected  by  a  veterinarian  in  the  employ  of  and  receiv- 
ing a  salary  from  the  Canadian  government,  and  be  accompanied  by  a 
certificate  signed  by  him  stating  that  he  has  inspected  the  sheep  and 
found  them  free  from  disease,  and  that  no  contagious  disease  affecting 
sheep  has  existed  in  the  district  in  which  the  animals  have  been  kept 
for  six  months  preceding  the  date  of  importation  ;  stating  also  that 
they  have  been  twice  carefully  dipped  under  his  personal  supervision, 
or  under  the  personal  supervision  of  another  veterinarian  in  the  employ 
of  and  receiving  a  salary  from  the  Canadian  government,  in  one  of  the 
dips  approved  by  the  Secretary  of  Agriculture,  as  described  in  Regula- 
tion 33  of  B.  A.  I.  Order  143.  The  owTner  or  importer  shall  present  an 
affidavit  that  said  certificate  refers  to  the  sheep  in  question:  It  is  pro- 
vided further,  That  any  such  sheep  which  are  unaccompanied  by  the 
aforesaid  certificate  showing  that  they  have  been  twice  dipped,  as  herein 
prescribed,  shall  be  subjected  to  a  quarantine  of  thirty  days. 

This  amendment  shall  become  and  be  effective  on  and  after  October 
20,  1909. 

James  Wilson, 
Secretary  of  Agriculture. 


Regulation  33  of  B.  A.  I.  Order  143,  as  amended,  which  is  referred  to 
in  the  foregoing  amendment,  reads  as  follows : 

Regulation  33.  The  dips  now  approved  are : 

(a)  The  tobacco-and-sulphur  dip,  made  with  sufficient  extract  of  tobacco  or 
nicotine  solution  to  give  a  mixture  containing  not  less  than  five  one-hundredths

of  1  per  cent  of  nicotine  and  2  per  cent  flowers  of  sulphur:  Provided,  That  for 
the  first  dipping  of  infected  sheep,  in  lieu  of  the  sulphur  herein  prescribed,  a 
sufficient  additional  amount  of  extract  of  tobacco  or  nicotine  solution  shall  be 
used  to  give  a  mixture  containing  not  less  than  seven  one-hundredths  of  1  per 
cent  of  nicotine. 

(&)  The  lime-and-sulphur  dip,  made  by  mixing  8  pounds  of  unslaked  lime  and 
24  pounds  of  flowers  of  sulphur  and  boiling  with  30  gallons  of  water  for  not  less 
than  two  hours.  All  sediment  should  be  allowed  to  subside  before  the  liquid  is 
placed  in  the  dipping  vat.  This  liquid  should  be  diluted  sufficiently  to  make 
100  gallons  before  use. 

And  pending  further  investigation,  the  following-described  dips: 

(c)  The  cresol  dip,  which  consists  of  a  mixture  of  cresylic  acid  J  with  soap. 
When  diluted  ready  for  use  this  dip  should  contain  one-half  of  1  per  cent  of 
cresylic  acid. 

(d)  The  coal-tar  creosote  dip,  which  is  made  by  mixing  coal-tar  creosote  or 
coal-tar  oils  and  cresylic  acid  separately  with  resin  soap  in  varying  proportions. 
This  dip  should  contain  when  diluted  ready  for  use  not  less  than  1  per  cent  by 
weight  of  coal-tar  oils  and  cresylic  acid.  In  no  case  should  the  diluted  dip  con- 
tain more  than  four-tenths  of  1  per  cent  nor  less  than  one-tenth  of  1  per  cent  of 
cresylic  acid;  but  when  the  proportion  of  cresylic  acid  falls  below  two-tenths  of 
1  per  cent  the  coal-tar  oils  should  be  increased  sufficiently 'to  bring  the  total  of 
the  tar  oils  and  the  cresylic  acid  in  the  diluted  dip  up  to  1.2- per  cent  by  weight. 

The  cresol  dip  and  the  coal-tar  creosote  dip  should  always  be  tested  on  a  small 
scale  with  the  water  and  under  the  conditions  to  be  employed  in  dipping  in  order 
to  avoid  possible  injury  to  stock.  The  diluted  sample  should  be  allowed  to  stand 
for  at  least  an  hour.  If  after  this  length  of  time  there  is  a  separation  of  an  oily 
layer  the  dip  should  not  be  used  with  that  kind  of  water.  Especial  care  in  this 
connection  is  necessary  where  hard  water  is  to  be  used. 

In  the  undiluted  coal-tar  creosote  dips  there  may  be,  in  cold  weather  especially, 
a  separation  of  naphthalene  and  other  constituents  of  the  dip.  Care  should 
therefore  be  taken  to  see  that  the  concentrated  dip  is  homogeneous  in  character 
before  using  any  portion  of  it. 

Manufacturers  wTho  desire  the  Department  to  approve  their  dips  for  official 
dipping  should  submit  a  sample  of  their  product  to  the  Bureau  of  Animal 
Industry  in  Washington  and  accompany  this  with  the  formula  used  in  prepar- 
ing the  dip. 

Before  a  proprietary  substance  is  approved  for  use  in  official  dipping  the  man- 
ufacturer must  agree  as  follows: 

(1)  To  recommend  for  sheep  scab  a  dilution  of  the  product,  so  as  to  conform 
to  the  requirements  of  the  Department  of  Agriculture. 

(2)  To  maintain  said  product  at  a  uniform  composition. 

(3)  To  place  on  packages  of  dips  which  have  been  examined  and  found  to 
conform  to  the  requirements  of  the  Department  the  following  statement: 

"A  sample  of  this  product  has  been  submitted  to  the  United  States  Depart- 
ment of  Agriculture  for  examination.  We  guarantee  the  contents  of  this  pack- 
age to  be  of  the  same  composition  as  the  sample  submitted  to  the  Department, 
and  that  when  diluted  according  to  the  directions  printed  thereon  for  the  treat- 
ment of  sheep  scab,  it  will  give  a  dipping  fluid  of  the  composition  required  of  a 

2  dip  by  the  regulations  of  the  Secretary  of  Agriculture  governing 

sheep  scab." 

(4)  To  have  on  containers  or  advertising  matter  no  reference  to  the  United 
States  Government  or  any  of  its  Departments  except  as  provided  in  the  preced- 
ing paragraph,  unless  such  reference  has  been  submitted  to  and  approved  by 
the  Department  of  Agriculture,  and  to  have  on  containers  or  advertising  matter 
no  false  or  misleading  statement. 

1  By  the  term  cresylic  acid  as  used  in  these  regulations  is  meant  cresols  and  other  phenols 
derived  from  coal  tar,  none  of  which  boils  below  185°  C.  nor  above  250°  C. 

-There  should  be  inserted  here  the  name  of  the  class  of  dips  to  which  the  product  belongs, 
such  as  "cresol"  or  "lime  and  sulphur,"  etc.
